Abstract (en)
[origin: US2012006255A1] A seed crystal having a frontside surface and a backside surface is prepared. Surface roughness of the backside surface of the seed crystal is increased. A coating film including carbon is formed on the backside surface of the seed crystal. The coating film and a pedestal are brought into contact with each other with an adhesive interposed therebetween. The adhesive is cured to fix the seed crystal to the pedestal. A single crystal is grown on the seed crystal. Before the growth is performed, a carbon film is formed by carbonizing the coating film.
